(FR) PROCÉDÉS D'EXÉCUTION D'UN ENCODAGE ET D'UN DÉCODAGE INTRAPRÉDICTION D'AU MOINS UNE IMAGE, ET DISPOSITIFS ÉLECTRONIQUES CORRESPONDANTS
Abstract:
(EN) In one embodiment of the disclosure, it is proposed a method for encoding of at least one picture, said at least one picture being decomposed into a set of blocks. Such method comprises an encoding of at least one block of said set of blocks using intra prediction, and said at least one block comprises pixel values corresponding to either the luma component (L) or chroma components (Cb or Cr). The encoding of said at least one block comprises: obtaining (1301) a set of local minimum and local maximum pixel values within said at least one block; encoding (1302) at least one position information of said pixels corresponding to local minima and local maxima within said at least one block; encoding (1303) pixel values of said set of local minimum and local maximum pixel values.
(FR) Un mode de réalisation de l'invention concerne un procédé d'encodage d'au moins une image décomposée en un ensemble de blocs. Ledit procédé comprend un encodage d'au moins un bloc dudit ensemble de blocs par intraprédiction, et ledit ou lesdits blocs comprennent des valeurs de pixels correspondant à la composante de luminance (L) ou à des composantes de chrominance (Cb ou Cr). L'encodage dudit ou desdits blocs comprend les étapes consistant à : obtenir (1301) un ensemble de valeurs de pixels locales maximales et minimales à l'intérieur dudit ou desdits blocs; encoder (1302) au moins un élément d'informations de position desdits pixels correspondant à des maxima et des minima locaux à l'intérieur dudit ou desdits blocs; encoder (1303) des valeurs de pixel dudit ensemble de valeurs de pixels locales maximales et minimales.
